Option A is the correct command set to configure an extra keyring in Cisco UCS Manager. The commands create a keyring named "extra" with a modulus of 4096 bits, which provides a high level of encryption. The commands also generate a self-signed certificate for the keyring, which enables secure authentication when users use the web interface. References:

When connecting a storage device directly to Cisco UCS Fabric Interconnects, the following configuration steps are required:
1. Create identical VSANs on each fabric interconnect:
VSANs (Virtual Storage Area Networks) are required to segment the Fibre Channel traffic, and they must match on both fabric interconnects to ensure proper connectivity and failover.
2. Set the Fibre Channel Switching mode to Switch:
In this mode, the fabric interconnect operates as a standard Fibre Channel switch. This is necessary for direct connections to storage devices because they expect to connect to a Fibre Channel switch rather than an NPV device.

The hybrid cloud model is the most suitable for the described scenario. It allows for a combination of local (private) cloud infrastructure with remote (public) cloud services. This model supports hosting the primary workloads in a local data center, utilizing remote data centers for backups, and provides the flexibility to scale out to a public cloud provider when necessary. The hybrid cloud model offers the benefits of both private and public clouds, including security, scalability, and flexibility, which aligns with the organization's requirements.
